Today it looks like I'm only getting 70g protein, I ran out of whey till wednesday.

1700 cals with a 2200 BMR, lifted today as well.

Probably nothing but everybody is different. I for one don't listen to the rule that you will lose muscle if you are not intaking 1g per body weight. I intake about 70-100g of protein daily on my cut and have not lost any muscle whatsoever, in fact have been getting stronger.

if you dont get enough calories for like a long period of time with low protein you can go into a catabolic state and break down your muscle for energy/proteins to make up for the calories you didn't get. make sure you can get enough protein help your muscles recover from lifting

For me when I was cutting from 235-170 currently, there were days where I would have under 50-80g of protein sometimes (many nights of drinking).

On average, I would have around 100-120g, and I was making gains with all lifts while steadily losing bodyfat.

I think your genetics mainly has a role on how it utilizes the protein you eat. For example maybe 50g of protein that I take will be utilized towards muscle repair/buildling MORE-SO than a ectomorph consuming 50g. Maybe some broscience there, but in my experience my body get's good gains with way less than 1 pound of protein/bodyweight.

So in other words, you will have to do some trial and error, see if you make gains with a certain amount of protein that you consume each day. Try and stick with that number consistently and dont fret if you get below it, or way below it some days. As long as you're consistent.
